S5, E1: Continuing from the season finale in the year's first new episode, a dazed Grace (Debra Messing) is rescued by a handsome Jewish doctor (guest star Harry Connick Jr.) who pulls her up on his horse and delivers her just in time for her insemination with an impatient Will (Eric McCormack). But their new relationship as expectant parents puts a strain on Will and Grace's relationship when they agree not to date until their baby is born. Meanwhile, a restless Karen (Megan Mullally) can't make up her mind about cheating on her imprisoned husband with the genteel but ardent suitor Lionel (guest star Rip Torn). Sean Hayes also stars.
